Parent and Cascade binding

- [ ] #36
- [ ] `data-cascade` attribute
- [ ] `data-parent` attribute
- [ ] use the attribute value as the depth of binding

```html

increment

```
same as
```html

increment

```
To turn off prefix `&`
```html

increment

```
It also possible to alias the parent data
- `data-cascade` aliasing still require prefix `&`
- `data-parent` aliasing doesn't require prefix `&`
```html

increment

```
- aliasing support glob or RegEx pattern, but to avoid repetitive RegEx compilation:
- RegEx pattern is detected if value startWith('^') or endWith('$')
- otherwise use simple glob pattern
```html

```
